AUTOMATIC SELF-CENTERING GUIDE EYE Filed Aug. 4, 1957 Patented Sept. 13,1938 UNITED STATES PATENT OFFICE John J. Dunleavy, Scranton, Pa.

Application August 4,

14 Claims.

This invention relates to thread guiding devices such as are used in thetextile art in connection with various types of winding machines.

The principal object of the invention is the pro- Vision of aself-centering guide used in connection with the winding of yarn andthread, principally silk and rayon yarn, and by the use of which pileyarn windings at the spool heads are eliminated.

A further object is the provision of an automatic self-centering guideeye provided with a projecting feeler arm which when it contacts withthe spool head releases the guide eye member from the action of thetraverse bar and wherein the guide eye is again automatically connectedto the traverse bar and properly centered.

A further object is the provision of a selfcentering automatic guide eyeby the use of which a more even wind is obtained through the winding ofthread or yarn particularly silk or rayon yarn and wherein any bulgingof the yarn at the heads of the spools is eliminated.

A further object is the provision of a device of this character whereina more even tension with a better wound spool of yarn or thread isattained and wherein in operation the yarn is in contact only with theusual standard porcelain guide eye carried by the guide eye clamp orholder.

A further object is the provision of a device of this character whereinproper centering of the yarn is always maintained and piling up of theyarn at the head of the spool is prevented.

Heretofore in guides of this character in this art it has first beennecessary to ascertain the proper position and location of the guide on.the traverse rail and after such position is ascertained the guide isadjusted along the traverse guide rail and set and remains fixed duringthe operation of winding.

My invention is the first wherein is provided an automaticself-centering guide eye for use in winding yarn or thread in windingmachinery.

My self-centering guide eye is shown in the accompanying drawing,wherein corresponding sponding parts in each of the several views.

In the drawing:-

Fig. 1 is a plan view of my device showing same attached to the traverserail and as used in connection with the spool on which the yarn is beingwound;

Fig. 2 is a rear face view of the device;

Fig. 3 is an end view;

I4, through which is passed a pin or rod I5. The 1 base plate I6 isrigidly secured to the traverse rail IT by means of screws or otherfastenings I800, that the guide I2 is caused to move with the traverserail," in both directions. On the inner edge of the plate H5 at each endis provided a loop or socket Ma which carries the pin I5. The loop orsocket I4 is shorter than the distance between the loops |4a to allowfor a sliding or lengthwise movement or play of the guide I2 when thefeeler arm or projection 2| contacts the head 24 or 25 of the spool.Projecting downwardly from the plate I3 from the front thereof is aportion l8 formed from the metal plate. The lower edge of thisdownwardly projecting portion is provided with teeth or indentations I9in which enter upwardly extending projections or teeth 20 on the baseI6.

It will thus be seen that when the teeth 20 are in mesh with the teethI9, the guide eye will be carried along with the traverse rail inwhichever direction the same is moving.

Projecting inwardly from the portion I8 is a feeler arm or projection 2|which, in the present instance is made adjustable as to its length bypassing the inner end of the arm through an opening in the plate l8 anddownwardly extending portion 22 of the plate l3. A spring 23 isinterposed between the plates 22 and I8 which normally holds the arm 2|projected outwardly.

The feeler arm 2| is made adjustable in order to take care of filled orpartially filled spools and is automatically shortened as the mass ofyarn on the spool increases.

It will thus be seen that when the feeler arm 2| contacts with the head24 or 25 of the spool, the spool revolving, due to friction the guidewith its clamp will be pivotally moved on the pin or rod I5 and releasedfrom the plate I6, which is carried by the traverse rail, and movedalong the rod, and automatically returned by gravity, into propercentering position, when it will drop and again mesh with the teeth 20and when the traverse rail starts in the opposite direction and reachesthe head 25 of the spool, if piling of the yarn is likely to occur, thesame operation will be performed and the same action take place.

It will thus be obvious that by the action of my self-centeringautomatic guide and the operation thereof, piling yarn windings at thespool heads will be eliminated.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States, is:

1. In a device of the character described, a traverse guide rail, aself-centering guide eye pivotally and slidably mounted thereon andmovable therewith, means normally holding said guide eye against slidingmovement on the rail, a winding spool for the yarn, and means adapted tocontact with the head of the spool and cause said guide eye to swing onits pivot and thereby automatically disconnect said guide eye frommovement with the rail.

2. In a device of the character described a traverse guide rail, awinding spool, a self-centering guide eye slidably and pivotally mountedon the rail and movable therewith, means holding said guide eye againstsliding movement on the rail, a contact arm on the guide eye adapted tocontact with the head of said spool and automatically disconnect theholding means to permit of relative movement between the rail and theguide eye. a

3. A device of the character described for winders, comprising a threadguiding member, a plate, means carrying said thread guiding memberpivotally and slidably mounted on said plate, means on said firstmentioned means cooperating with means on said'plate for normallyholding said thread guiding member against sliding movementon the plate,and means for releasing said holding means to permit of relativemovement between the plate and thread guiding member.
